Abstract
This paper presents an energy-ef ficient processing
platform for wearable sensor nodes, designed to support diverse
biological signals and algorithms. The platform features a 0.5
V–1.0 V 16-bit microcontroller, SRAM, and accelerators for
biomedical signal processing. Voltage scaling and block-level
power gating allow opt imizing energy ef ficiency under applica-
tions of varying complexity. Programmable accelerators support
numerous usage scenarios and perform signal processing tasks at
133 to 215
